PROCESS FOR MAKING PETROL 0R GAseLENE.

Specification of Letters Patent.

Patented June 22, 1920.

Application filed December 8, 1910, Serial No. 596,382. Renewed May 18, 1920. Serial No. 382,335.

To all whom, it may concern:

Be it known that I, CHARLES R. BURKE,

citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in Processes for Making Petrol or Gasolene; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

y invention consists of certain new and useful improvements in the art of making petrol or gasolene, whereby a product is obtained having a greater number of thermal units, and at a reduced cost of production.

My process consists in distilling crude oil in any well known manner and preferably under from twenty-five (25) to one hundred (100) pounds pressure, and then mixing, with the resulting vapor, natural gas, then compressing the combined vapor and natural gas and then condensing said mixture; the product will be my improved gasolene. The amount of pressure in the still depends upon the character of the material with which the still is originally charged and is to be determined by experiment with each different quality of oil to be distilled.

The vapor from the still may be carried to a mixing chamber into which natural gas is also introduced, and thence with the gas to a compressor by which the mixed vapor and gas are compressed. The compressed vapors are then led to a condenser where all possible condensation is effected and the condensate is then run off into a receiving reservoir from which it may be drawn for use. The reservoir is provided with a pressure valve which registers the amount of pressure in the condenser, and the amount of pressure is determined by the desired quality of the condensate.

In carrying out my process, I may find it desirable to distil the crude oil one or more times, passing the resultant vapors of-the first distillation through a condenser into a container, then distilling the product of the first distillation in the same way, and so on, distilling the product'of the last distillation under varying degrees of pressure as has already been stated, after which the natural gas may be mixed with the vapor or gas derived from the steps. of my process just described and the combination of the vapor and natural lene.

The natural gas is preferably mixed with the vapor before the latter enters thecondenser and may be forced into the condenser gas is then condensed into gasounder a pressure equal to or exceeding the gas and condensing same under pressure into gasolene.

In order that my invention may be clearly understood I have illustrated diagrammatically one form of apparatus which may be used for carrying out my process, in which similar letters of reference indicate identical parts.

A is a still, constructed of any suitable material, which is capable of withstanding an internal pressure of from twenty-five to one hundred pounds to the square inch. B is a heating means of any desired form for heating the contents of the still.

C is what I may term a mixer, and consists of a chamber or compartment, constructed of any suitable material in which the vapors from the still are mixedrwith natural gas. The temperature of the chamber C is maintained preferably at a .temperature of about 300 Fahrenheit.

a, a, a are tubes leading from the still to the mixing chamber, and in the tube a I provide a pressure valve D. E is a tube which is connected with an oil well and through which natural gas may be inducted to the mixing chamber C under a pressure sufficient to force the gas into the said chamber. F is a condenser of usual form and G is a pump for drawing the vapors from the mixing chamber C into the condenser F through suitable connections I, K, the pressure exerted by the pump or compressor being regulated by the specific gravity desired for the resultant product.

It will be understood of course, that there are suitable check valves arranged in the pipes between the condenser and pump and mixer and pump to permit the vapors to be drawn by the pump from the mixer and forced into the condenser, but preventing vapors being withdrawn from the condenser and forced back into the mixer. 4

H is a reservoir for receiving the product which is gasolene, from the condenser. The reservoir is also provided with a pressure valve K.

In operating the above described form of apparatus, oil is placed in the still, and the pressure valve D adjusted so as to permit the discharge of vapor into-the mixing chamber at a given pressure which may be from twenty-five to oneshundred pounds. Heat is then applied to the still and distillation ensues.

There is necessarily some pressure in the mixing chamber C and I preferably arrange to force natural gas into said chamber simultaneously with the admission of vapor from the still, andthe said vapor and gas are there mixed. The mixture is then forced into the compressor and thence into the condenser and the condensed product or gasolene run off into reservoir H.

As formerly stated, I may distil and redistilthe crude oil until a vapor of sufiicient lightness is obtained before mixing the same with the natural gas in the mixing chamber.

Broad claims covering the same general subject matter of this invention, are being prosecuted in a co-pending application.

What I claim and desire to secure by Letters Patent is l. The process of making gasolene from 3. The process of making gasolene from-1 heavier hydrocarbon oil which consists in distilling such heavier hydrocarbon oil, then mixing natural gas with the vapor resulting from said distillation, then passing the combined vapors through a compressor, as heretofore described, and then condensing the combined condensible vapors.

In testimony whereof I aflix my signature, in the presence of two witnesses.

CHARLES R. BURKE.
